Improvement in grates for stoves



UNITED STATES WILLIAM L. MCDOWELL, OF PHILADELPHIA, PENNSYLVANIX.

IMPROVEMENT m GRATES; FOR STOVE-S.

T0 (LZZ whom it may concern;

Be it known that 1, WILLIA L. McDow- ELL, of the city of Philadelphia, in the State of Ienns lv'aniafliave invented a new and useful Improvement in Vibrative Grates for Coal-Stoves and other Small Furnaces; and I,

' do hereby declare that the following is a full,

clear, and exact description of the construction and operation of thesanie, reference being had to the accompanying drawings, making a part of this specification, in which Figure 1 is a plan view of ,the base of a common cylindrical stove having the improved grate applied thereto; Fig. 2, a like view of the grate detachcd; l*ig. 3, a central i transverse section of the middle bar of the said grate and of its supporting-bar; Fig. 4, a front edge view of they grate havingits handleeut transversely through at the dottedline w of Fig. 2, and Fig. 5 a; sectional plan .view of the grate without its draw-bar. f g Like letters indicate the same parts when in the differentfigurcs. 'The nature of my invention-consists, substantially as. hereinafter described and specifiedyin combining a draw-bar with a horizon tally-vib1'ativc' -grate in such a manner that whileeach of the spaces between the bars of the gratewill be free to allow'anunobstructed course for the passage of the raking end of a hand-poker from the front to the rear side of the fire cylinder orchamber a free vibrativc motion can at any time be given to the grate,

" whether the draw-bar'beeither in place or withdrawn thercfro1n,"'thus enabling the ,op-

erator not only to rakc'th'e fire more perfectly -by means of a poker, but to dischargev the stones and cinders by vibrating the grate.

In the drawings, A is the grate; B, the base of an ordinary cylindrical coal-stove, and G the supp'orting-llange'for the fire-cylinder of the same. 7

The center bar of A the grate A is provided with a hollow boss, a, which fits upon a stud or pivot in'tl'ie middleofa supporting-bar, I), fixed to the base B, so that the grate will be supported by and allowed to be turned or vibrated upon the said stud in the bar b in the usual manner. The front edge of the grate has a handle, (a, which projects through a long horizontal; slot, b, .in the front of the base in the fisual manner. The handle ais divided horizontally into two parts, the lowerlpart part fits accurately over the lower part and extends back from front to rear of the grate inthe -form oftwo connecting grate-bars, a

a", the-circular boundary or rim a of the grate being 'depressedacross itsupper side, as at a, Figs. 4-a-nd5', for the reception of the same, so that its handle and bars shall, when applied, come flush with the upper surface of the grate-rim. This upper or movable portionof the grate A constitutes the draw-bar.

The lower half of the handle a has a straight longitudinal slot,- a", into which a stud, a, on

the under side of thcnpper half of the saidhandle a fits, so as to serve, in connection with the sides of the draw-bar and the shoulders of the depressed parts a of the grate-rim, to guide the bar properly in introducing it through the.

slot b of the base B.

Operation: It will be seen that in this im-' proved grate'there is not any transverse obstructing bar whatever to intcrl'ere;with or prevent a free backward and iorivard motion 0t the hooked endof' a poker in raking the v fire, and that the spaces between the grate- .bars are each open entirely from front to rear of the fire cylinder or chamber; that a free and effective vibrative motionrcan be given by meansof the handle to the gratewhether and cinders by simply vibrating the grate by means oft-he remainingpart of the handle-ea combination of advantageous fllllCtiOllSflVhlCl], itis believcd cannot be foundin any other grate.

,I wish it to be understood that I do.not in I tend to confine myself to the particular mannerjdescribed and set forthot' combining the draw-barv with the grate; but,

Having fully described'my invention and pointedoutitsutility, and also what I believe to be the best'modeof carrying itoutin practice, what I claim as new, and desire toQsecure by Letters Patent, is-

p The combination of a draw-bar with a vibrative grate, so that it shall form a moving part of thesamc and operate substantially as .de scribed, for the purposes specified.
